Forum: prelinger Subject: That pesky 368x480 resolution...

Yes, I know, I've posted about this in the past...how unfortunate that so much of the best stuff on this site was encoded at a resolution that's completely incompatible with DVD, SVCD, VCD, and just about any other spec you can think of. However, it will play in Winamp. Yay.

I tried converting these files to 352x480 using TMPGEnc, and they come out a bit jerky and frame-draggy/strobey. Has anyone here had success with converting these files to a DVD-compliant resolution and had them come out running as smooth as they went in? Or am I resigned to the frame-dragging if I want to burn them to DVD-R?

Even though I have a DVD burner, for watching Archive films on my stand-alone (TV) DVD player, I download the MPEG2 files, then run them through my freeware MPEG-1 encoder and make high quality, standard resolution MPEG-1 files which I burn on CD.

The MPEG-1 files of films here are mostly encoded below standard resolution (320x240 instead of 352x240) and are very blocky because they were not encoded in high-quality mode.

Another thing I've noticed here that irks me is that some MPEG-2 files are damaged and will not re-encode when run through the encoder. Likewise, some of the MPEG-1 files I've downloaded here have data errors, too, which cause the files to crash when played on my DVD player. I know it's the video files because I get errors when I play them on my PC as well.

Hi! I've been enjoying the films for a couple of years now and have finally found a working formula for all the films-this took many hours of trial and error, frustration. The ULEAD Studio for windows will convert absolutely every file on the archive to DVD compliance, both the sound and picture. And the results are stunning! I screwed with TMPEG for a long time, only to find it freezing on imperfect frames and staying frozen for the rest of the film. If you get the Ulead 30 day trial on the web, you can reencode any of the films. I still use TMPEG, but after fixing files with ULEAD first, because Ulead fixes the "Mpeg stream" and is then further editable (contrast, focus, color, etc.) A huge problem several years ago (they did a lot of work on this) was that the films had no standardized volume, so some would blast while others were nearly inaudible. I would use TMPEG for volume fixes because you can see a picture of the sound in the edit window and more quickly edit it than guessing with Ulead.

Downloaded Ulead VideoStudio 9.0, and used it to convert Good Eating Habits from the archive. Results: even worse than TMPGEnc. The video still turns out strobey, plus now there's no soundtrack. It's been replaced with noise, like you hear on a radio with no reception. What am I doing wrong? These files are driving me INSANE...

Hmmm..Maybe the source file's no good. How fast are you burning the disk? Trying to think, are you saving the edited file as a DVD file? And what software are you using to burn with? Seems like there are a lot of factors. Even the brand of blank, as well as the DVD player itself can affect things. Win 98? XP? Truth is I have been using Ulead Version 8 and the results look like another channel on television.. trial and error. Make sure the file doesn't get edited a second time if you are using Nero to burn with, there is a bypass option called smart encode which takes your word for it that the file is ready to go without being resampled. When I use that it makes the disk very quickly! Good luck! If you are in Europe, they have a 24 frame per second setup instead of North American 29.95 frame NTSC. That could seriously affect things if that's a factor.

No, the source file is fine. I don't know why I'm having this problem...

It's too bad that so many of the best files on this site are screwed up. If I could get them to convert properly to a compatible resolution, I'd be more than willing to download and convert and upload corrected files. Might be a worthy project for those who are tech-savvy enough. I wish I was.

One thing that would be incredibly helpful is if there could be a notation next to the download link of all the files that are in the incompatible 368x480 resolution. Of course, that would probably take eons to do.

Oh yeah, there's a bunch of files encoded at 480x480 as well, an equally incompatible resolution. Sigh...

The files you've got at 480x480 may work just fine in your DVD player since many players will handle SVCD's just fine. You might have to transcode the audio to 48K if it's not already. Try one out on a DVD-RW and see how it goes !

I think that's what TMpeg views as 1:1 SVCD. It would be great if the files were all set to DVD res for the Mpeg-2 and have the volumes normalized. We are all on our own. At least it makes a helluva crash course in digital A/V!

Hi. This is Rob from collections. Our encoded files come from various sources, so the formats do vary. However, most of the MPEG2 files should be DVD compliant. The easiest way to check is to look at the res: If it is any of 720x480, 704x480, 640x480, 720x576, 704x576, 640x576, or 352x480, it is a DVD compliant resolution. If it's one of those, it's very likely that the audio codec is standard, and that the stream is a bitrate that a DVD player can handle (<9.8Mbit combined). I can't really provide specific details on how to do this (as software varies), but if you split the mpeg2 file into 1gb chunks and import that into a DVD authoring program, you should be able to produce a working DVD.

At this time, none of our MPEG-1 files comply to any sort of standard. It might be possibly to convert some of these into VCD or DVD format, but the quality drop of transcoding would be very apparent.

Trying to convert MPEG-4's for burning would be absurd :-p

FYI, Rob and others, a lot of the earlier Prelingers were accidentally recorded in 368*480 (this was VERY early on before anyone had DVD burners, etc, tho!), so that's the problem in hand.
